How the iGaming Industry Works
Behind a single spin or bet sits a supply chain of specialised companies, none of which does everything alone. This lesson follows a game from the studio that built it to the screen a player sees, and follows the money back the other way — so you can read the industry as a value chain of distinct roles rather than one faceless "casino."
- Name the seven core roles in the iGaming value chain — players, operators, game providers/studios, aggregators, payment providers, affiliates, and regulators — and say what each one contributes.
- Trace a single wager as it becomes gross gaming revenue (GGR) and gets split between the parties who earn a share of it.
- Explain the difference between a B2C business (an operator facing players) and a B2B business (suppliers behind the scenes), and why a regulator sits above the whole chain.
The player and the operator: where the two sides meet
At one end is the player: an adult (18+ in most regulated markets, sometimes 21) who deposits money and places a wager. At the other end is the operator — the brand on the website or app, such as an online casino or sportsbook. The operator is the business-to-consumer (B2C) face of the industry: it holds the customer relationship, runs marketing, handles deposits and withdrawals, verifies identity and age, and is answerable to regulators for how players are treated. Crucially, the operator usually does not build its own games or payment systems. It licenses and assembles them from other companies. Think of the operator as a storefront and a landlord combined — it curates a shelf of games it did not manufacture and takes responsibility for the shop floor where players spend time and money.
Who makes the games: studios, providers, and aggregators
The games themselves come from game providers or studios — business-to-business (B2B) firms that design slots, live dealer tables, and other titles, including the mathematics that governs outcomes. A studio rarely wants to negotiate a separate technical integration with every operator in the world, and an operator rarely wants to wire up hundreds of studios one by one. Enter the platform aggregator: a middleman that integrates many providers once, then offers operators a single connection to a large game catalogue. This is why the same popular title appears across many different casino brands. Each layer specialises: studios focus on building and certifying games, aggregators focus on distribution and technical plumbing, and operators focus on players. Certification by independent testing labs checks that a game's declared odds and return-to-player behave as stated.
Following the money: GGR, and who earns what
Money flows opposite to games. Over many bets, a game is designed to pay back less than the total staked — that built-in gap is the house edge, and it is why the operator, not the player, is the reliable earner. The industry's key number is gross gaming revenue (GGR): total wagers minus total winnings paid out. From GGR, parties who earn a share get paid. Game providers commonly take a revenue share — widely reported in the range of roughly 7–20% of GGR for standard slots and table games — often split with the aggregator that distributes their content. Payment providers (PSPs) charge fees to move deposits and withdrawals. After bonuses, taxes, and these costs are deducted, what remains is net gaming revenue (NGR), the operator's truer bottom line. No honest description of this chain implies a player comes out ahead; the model depends on players, in aggregate, losing more than they win.
Affiliates and regulators: traffic in, guardrails around
Two roles sit at the edges. Affiliates are independent marketers who send players to operators and are paid for results — typically via CPA (a fixed fee per qualifying new depositor), revenue share (an ongoing cut of the player's NGR), or a hybrid of both. They earn only when they deliver customers, which makes them a large but tightly measured marketing channel. Around everything sits the regulator: a government-authorised body such as the UK Gambling Commission or the Malta Gaming Authority that issues licences, audits fairness and anti-money-laundering controls, enforces age verification, and mandates responsible-gambling tools. Regulators license both B2C operators and B2B suppliers, and a licence is jurisdiction-specific — legality depends entirely on where the player is located. The regulator is the one party in the chain that does not want revenue from players; its job is to keep the rest of the chain honest and safe.

- Origins: In 1994 Antigua and Barbuda passed the Free Trade & Processing Act, enabling licensing of online gambling operations; Microgaming's 'The Gaming Club' is widely cited as the first online casino (developed 1994, full operations reported from 1995). 'First' claims are contested across sources, so treated as 'widely recognised' rather than definitive. Source: AskGamblers History of Online Gambling; Medium/Tina Rozman.
